One of the most talked about fights this decade took place in 2013, and later this month the combatants will run it back.

Union-Endicott graduate Jon Jones (21-1 MMA, 16-1 UFC) and Alexander Gustafsson (18-4 MMA, 10-4 UFC) first met in September 2013 at UFC 165. They went the distance in a thrilling slugfest, and Jones managed to hold on to his light heavyweight title with a unanimous decision. Jones had a pair of 48-47 scores and a 49-46.

But in the more than five years since then, many have said the fight was the closest Jones has come to looking vulnerable in all his time spent in the octagon, which makes the rematch an intriguing one.

Jones and Gustafsson will fight for the 205-pound title, which will be vacated by current dual-champion Daniel Cormier as soon as the bell rings on their fight. The title fight is Jones’ first since serving a 15-month suspension for his second-anti-doping violation, which stemmed from a failed steroid test following his knockout win over Cormier at UFC 214. The victory was later overturned to a no-contest.

But before the rematch at UFC 232 at T-Mobile Arena in Las Vegas on Dec. 30, watch the first fight in full below.
